Specification of Letters Patent.

Application filed October 31, 1914, Serial No. 869,513. Renewed October12, 1916. Serial No. 125,288.

has for its principal object certain details of construction embracing anew principle a of operation by means of which a complete removal of theouter skin or peel of the fruit or vegetable is insured without unduemarking or cutting away of the fruit or vegetable.

Referring to the accompanying drawings, Figure 1 illustrates alongitudinal sectional view with parts broken away' showing oneapplication of my invention. Fig. :2 is a plan view of a machine partlybroken away such as shown in Fig. 1, and Fig. 3 a cross sectional viewof such a machine. Fig. is an enlarged detail of the carrier mechanismshowing a potato in position therein. Fig. 5 an enlarged detail of oneof the cut ting mechanisms. Fig. 6 a combination view of Figs. 1- and 5showing the relative position of one of the knives while in the act ofcutting away the skin or peel of the potato. Fig. 7 is an enlargeddetail in plan view showing the end of one of the knives such asillustrated in Figs. 5 and 6. Fig. 8 illustrates a side view of one ofthe stationary knives. Fig.9 a front elevation of the same, and Fig. 10a similar view to Fig. 9 with the end of the knife laid out flat. Fig.11 is a similar view to Fig. 3 showing certain modifications, and Fig.12 is a plan view showing certain modifications of the fruit orvegetable carrying frame.

13 is the main chamber of the apparatus which is fed through the hopper1 1 into which the potatoes or other vegetable or fruit are introduced.The same are fed by gravity through the centralizing guide 15 which itwill be observed is concentric with the frames such as 16 mounted uponthe shaft 17 by any suitable means such as the binding screws 18. Theseframes are shown to better advantage in Fig. 3 in which it will be seenthat they are preferably oval in cross section .and are provided withcentral bearings such as 19 secured by the connecting bars 20. Oppositesides of opposite connecting bars 20 are also preferably provided withteeth such as 21 which are adapted to penetrate the surface of thepotato to hold the same from shifting while being acted upon by theknives although as will be hereinafter disclosed, the potato is in factadapted to shift in a general rotary and forward manner through themachine.

Within the chaihber 13 is also preferably longitudinally securedsuitable supports or bars such as 22-23 upon which is preferably securedcutters such as 24l-25 respectively having turned over cutting edges asindicated at 2627 so that as the potatoes advance rightwardly throughthe machine shown in Fig. 1, the skin of the potato is engaged by theopposite knife edges 262 and thrown therefrom dropping into the bottomof the chamber 13 and discharging through the opening 28 in the basethereof.

The knives such as 2425 it will be observed are not mounted at rightangles as shaft 17 but are projected slightly rightwardly. It will alsobe observed more particularly with reference to Figs. 8 to 10 inclusivethat the cutting fingers such as 2930 and 31 of the knives thoughparallel and preferably of equal length are preferably resilient andindependently movable so that as the potato revolves within the framessuch as 16 the fingers engage the potato thereby imparting thereto arotational movement about an axis at right angles to the axis 17 and atright angles to the path of the potato in being carried within theframes 16, thus insuring contact with every point on the surface of thepotato and in suring a complete removal of the skin or peel therefrom,allowing the ends of the fingers such as 29 to 31 inclusive because oftheir resilient character, to ride down into any depressions or recessesof the potato so as to cut out the eyes and insure a clean peeling.

Referring now to Fig. 3 it will be observed that two other shafts suchas 32-33 are adapted to be rotated by the main gear 3% mounted upon theshaft 17 which carries sprocket and chain 3535 or other suitableconnection. Upon the said shafts 32 33 may be mounted suitablesupporting blocks such as 36 provided with arms such as 37 to which maybe secured knives such as 38 by means of a rivet, screw or othersuitable fastening at the base such as 39 and by means of the adjustablering such as d0 to vary the resiliency or action of said knives. view ofone of these knives is shown to better advantage in Fig. 7 in which itwill be seen that a suitable cut away portion such as 4-1 may beprovided, one side of which is preferably provided with teeth such as 42which insures engagement with the skin of the fruit or vegetable. Theend of the knife it will be observed terminates in a return portion 43which strengthens and reinforces the same and which may be formed out ofthe samepiece or may be suitably secured thereto by solder or othersuitable means. As the knives 38 rotate in opposite directions, the endsof the same pass between the potatoes and between the adjacent rings orframes 16 within which the potatoes travel and tear the skin from thepotato as the same leaves contact therewith and continues in its path ofrotation.

While I haveillustrated and suggested that the knives 37 may be rotatedas aforesaid, I do not wish it to be understood that this invention isso limited as I have found that very good results may be obtainedwithout the use of the knives 37 or any other parts associated therewithand have found by eliminating the same I am still nevertheless able topeel potatoes completely and cleanly by the use of the stationary knives24-25. However, the knives 37 may be mounted as shown in Fig. 11 whereinit will be observed that these knives are mounted permanently within thechamber 13 and have no movement except that permitted by virtue of theirresiliency and by virtue of their contact with the revolving fruit orvegetables within the rotating frames.

For the purpose of cleaning out the interior of the machine I mayprovide any suitable means such as the longitudinally mounted pipes 4Aprovided with spraying nozzles such as L5 through which water or anyother material may be fed as by the pipe A plan- 46 and allowed to drainwith the peels through the discharge opening 28 at the bottom, thepotatoes as peeled being preferably discharged through the chamber &7

from which point they may be caught in a of the apparatus withoutdeparting from;

the spirit of the invention as claimed.

I claim:

1.. In an apparatus of the class described,

the combination of a rotary feeding device,

stationary stripping mechanism cooperating with said feeding device,said stripping mechanism including flexible arms adapted to cooperatewith the vegetables, said arms having. cutting portions adapted to catchthe skin and tear the samefrom the vegetables and means tooperate saidfeeding device, said flexible arms provided with fingers of equal lengthand mounted so that said fingers engage the skin of said vegetablessuccessively, and means in combination with said rotary feeding devicefor controlling the movement of said vegetables while passingtherethrough and while being operated upon by said cutting portions.

2. In an apparatus of the class described, a conveyor comprising aseries of rotatable rings through which the vegetables are adapted to befed, and fixed resilient cutting members projecting between said ringsadapted to operate upon said vegetables as the same are fed throughsaid'rings, and means in combination with the last of saidrings forretarding the discharge of the vegetables therefrom.
